The 3s 23p 2 P--3s3p 2 4P Intercombination Lines of Fe XIV in the Sun
Abstract
The EUV spectra of solar flares obtained with the Naval Research Laboratory's S082A slitless spectrograph on board Skylab were examined, and the five components of the Fe XIV 3s2 3p 2P-3s3p2 4P intercombination multiplet were previsionally identified. A comparison of the observed Fe XIV line intensities with theoretical predictions reveals good agreement between theory and experiment, which tends to confirm the identifications and those made previously by Trabert, et al. (1987). The potential usefulness of the lines as electron density diagnostics is briefly discussed.
